TLDs
Web address suffixes
TLDs is the plural of TLD, short for top-level domain—the final segment of an internet address, following the last dot.
The original TLDs like .com, .org, and .net have been joined by hundreds of others: country codes (.uk, .jp), specialized domains (.edu, .gov), and newer options like .io and .pizza.
The company bought the same name across multiple TLDs.
